This is a puzzle program which will appeal to all those who can do the Rubik cube without thinking.
Even though it is in two dimensions, instead of Rubik's three, it is a frustrating and difficult task.
On loading, the screen displayed a set of control instructions in the top left quarter, a 10 by 10 grid below them and a set of regular shapes on the right half of the screen.
Each of these shapes can be rotated, and the object of the game is to place all of them on the grid, like a jigsaw.
Response is fast, the display is clear and easy to understand, all the options you could want are supplied and are easy to use. Instructions are also supplied on the colourful cassette.
Unfortunately, I am old enough to remember this game's predecessor, called Polynomials and played with low-tech card of hardboard shapes. However, I prefer Lojix, as the pieces do not get jogged out of position or lost.
For every game sold, 50p is put in the bank. The first sender of a solution will win the lot. A game for the thinker - and I'll bet it will be a while before the cash is won.
